Second, make sure your fiducial data for pick and place programs are built from CAD data and NOT manually at the machine.

Third, if component placement is off, fix the machine (i.e. calibrate, check cleanliness of lenses and sensors, damaged nozzle) and not the CAD locations.

Christian We'd guess that Evtimov and Wrongway mean that you should heed the process instructions / work instructions / process documentation

Fourth, if groups of components are off, but all others are on, check for either calibration (one head only) or a damaged nozzle (or similar items).

Maybe the fabricators of RAM chips will give you the design for a DDR3 circuit board. Why not? I would help fuel demand for their product. Try: * Samsung * Toshiba * AMD

Try using Chip Quik to reduce the heat required for component removal. Along with your bottom pre-heater, use a temperature controlled hot air system to help heat up top side for component installation. http://www.pcb-repair.com/products.htm

Hege, Yes. Good info. We have other products that run lead free process with known non-RoHS compliant components. All of these are using LF process compliant fabs however so this is the first time we have been in this position. Thanks.
